Is abnormal koyo bearing abnormal way of dealing with problems

Koyo bearing a lot of the reason of failure in addition to the normal fatigue spalling like failure caused by sealing, too close coordination with the factors such as poor lubrication bearing clearance or too small can traces of special failure and failure modes. So check the failure of the bearing can be found for most of the time the cause of bearing failure so as to take timely measures. In general bearing the loss of dynamic bearing in use process because of itself quality and external conditions, the bearing capacity, rotational accuracy and wear-resisting performance will change. When the low performance of the bearing will halt, appear to wait for all sorts of anomalies, loss of function therefore need causes were found in the short term, and take corresponding measures. 1. Because koyo bearing into the fatigue spalling belongs to the normal failure; 2. Because the cause poor lubrication failure 3 in advance. Because of pollutants into the shaft rolling bearing is a bearing noise itself, namely bearing the inherent noise; The other is a bearing installed before the noise, has nothing to do with the noise of the bearing itself. Tremolo ( All kinds of bearing) There is a certain frequency of sound, is due to large raceway surface waviness caused by vibration and the bearing or incorrect installation bearing failure in advance. In general is abnormal bearing has the following seven kinds of common symptoms: overheated bearings, bearing noise is too big, big bearing life is too low, vibration, short of machine performance requirements, bearing loose on the shaft, shaft rotation difficult. In general, koyo bearing grease filling amount, in the bearing temperature rise quickly. Although most redundant grease at the beginning of the operation is being squeezed out, the in the early stages of the bearing until all redundant grease were discharge, may be called the grease running-in stage, according to the structure of the bearing grease factors such as quality, filling quantity, this paragraph of time may last ten minutes, or even a few hours. The rest of the rest of the grease is completely after discharge, a small amount of grease in the rolling element and raceway, maintains contact with each other, are heavily dependent on the film of grease. In addition, in the process of bearing long-term operation, rolling element and raceway profile near detachments and keep on the shelf to atrophy and grease base oil, flow into the race, between supplement to lubrication also to have certain effect. Bearing is hole clip flat ( Hole hole roundness is not good, or distortion is not straight) And the bottom surface of the bearing pad iron uneven ( Lead to a hole deformation even crack of bearing seat) Bearing hole with sundry ( Residues have chip, dust, etc. ) Bearing clearance is too small, too tight (when rotating Set set of tighten too far) Insufficient lubrication ( The oil level is too low, the oil or grease seal leakage) Bearing clearance is too small ( Choose the wrong) Seal eccentric ( Touching the adjacent components and friction) Imported bearing raceway groove sound sound and its control method is when bearing is running, rolling on the surface of the raceway of the rolling element and a line of continuous sound, is unique to occur in all rolling bearings of the basic sound. General bearing ring raceway is combined with other sounds. Ball bearing raceway is irregular, frequency above 1000 hz, its main frequency does not change with speed, but its total sound pressure level increases with speed to speed up. Raceway big koyo bearings, the rolling sound of sound pressure level decrease with the increase of the viscosity; The raceway small bearings.
